UNI'I'ED` STATES PATENT OFFICE 14 Claims.

iis invention relates to window construction and more particularly to improvements in double hung windows which are capable of pivotal m0ve ment.

Prior to my invention it has been proposed that the inside section of a double hung window be mounted for pivotal movement but such prior arrangements have been unsatisfactory and they have been designed for awkward operation and effect improper results insofar as protection from the elements is concerned.' It has also been pro-` posed that both sections of a double hung window be arranged for pivotal action, but such constructions have not met with success for their design was bulky, they did not afford the proper protection and they interfered with storm windows and screen installations. These prior swingable or pivotal double hung windows, it has been found, have been expensive to manufac ture, require service by skilled technicians, are difcult to install, involving a redesign of conventional framing.

- It is an object of my invention to provide a relatively simple double hung window, in which the frames are swingably mounted to facilitate their movement into a room for washing, painting or other purposes. It is another object of my invention to provide a double hung window, the frames or" which are swingably mounted, effective to give proper protection from the elements.

It is a further object of my invention to provide a series of parts or structural elements with which an unskilled workman may convert a double hung window of conventional design to one in which the sashes are pivotally mounted.

Other objects and the nature and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawings, wherein:

Fig. 11 is a fragmentary view of a modified form of the elements illustrated in Fig. 8;

Fig. 12 is a fragmentary view in perspective of a locking mechanism used in connection with the window construction;

Fig. 13 is a fragmentary view, partly in elevation, and partly in section of a locking mechanism used in connection `with a lower sash; and,

' Fig. 14 is a perspective view of a base on which is mounted several elements which may be used in connection with the conversion of conventional window construction to a form in accordance back of the jamb 29 balancing Weights which may comprise solid cylindrical elements W fabri-` cated of steel or lead or bags of lead pellets or small steel balls, not shown, and at their other ends to the upper sash 2l` and the lower sash 28, respectively.

Secured at the rear outside portion of the jamb 20 is a xed vertical stop or guide 29 with which the sash 2l cooperates when in vertical sliding position. Also, cooperating with the sash 2l is the stop or guide 39, comprising the stationary xed portion 39a, and movable, resiliently mounted portion 39h which will later be described in more detail. The` guide or stop 39 has adual function, not only is it associated with the `upper sash 2l, but it also engages the outer side of the sash 28, whereby movement of this sash upwardly or downwardly is facilitated and protection from the elements is effected by the sealing of the Win dow along the line between the side edge of the sash and the face of the jamb 25. Also, associated with the front or lower sash is a stop or guide 3l, the upper portion 31a of which is iixed or stationary and has a cutaway portion 32. The lower portion Sib of the stop or guide 3l is pivotally mounted at 33 to the lower portion of the jamb 25, and has its upper portion 35 so contoured as to engage the cutaway portion 32, when the lower portion 3H) of the stop or guide 3l is elevated to place the sash 28 in operative position.

To secure the portion 3Ib in that position in which the sash 28 is in vertical sliding condition, the spring lock 35 is provided. 'This lock, see Fig. 13, comprises a spring element 35 housed within the stop portion 3 Ib and arranged to urge the lock element 37 outwardly. Secured to the lock 3l and mounted externally of the portion ,Sib is an operativev member 38 which may be moved downwardly with the linger to disengage the portion 3l from the corresponding receptacle 39 within the stop or guide portion 3m. It will be seen from the. above that the lock 35 will automatically secure the portion 3117 to the portion 3 la when the stop portion 3th is raised into operative position and into engagement with the cooperative portion 3 la.

To secure the jamb section 2l to the section 22, a pair of locking means 4l), see Fig. 8, each comprising a sheet preferably of metal, bent to form a right angle section having a leg and a leg 42, is secured to the section 2l by fastening means i3 which may be screws or the like. To provide for the engagement of the stationary Y jamb portion 22 with the locking means Ml, a

slot lli may be formed therein, by saw or other suitable means. The section of leg l2 of the locking means 4D when in operative engagement with the jamb section 22 is along the rear wall 45 of this section and the leg @l is within the slot 34. The Xed jamb section 22 may or may not comprise a lower removable portion 22 secured by screw or other fastening means F.

A modified form of locking means between the jamb section 2i and the jamb section 22 is illustrated in Fig, 11, wherein .a peg 43 is se cured to jamb section 2la for cooperation with the corresponding hole 45a and the flat plate lila secured to the jamb section Zia is arranged to cooperate with the rear wall 45a `of the jamb section 22a. As described in connection with Fig. 8, the xed jamb section 22al may or may not comprise a lower removable portion 22a secured by screw or other fastening means F.

Formed within the removable jamb section 2l are the grooves lll' and 58 with which the sashes 2l and 28 cooperate respectively. Secured to the lower portion of the sash 28 is a round peg 49 which may be formed of wood or metal for cooperation with the groove 58, whereby when the sash 28 is in its vertical position the pin 49 will slidably engage the groove and when the sash is in its lowered position swung down as in Fig. l, the pin 49 will act as a pivot point. Pivotally secured to the lower portion of the sash 21 by means of pin 55 is sliding block 5I which slidably engages groove 5l whereby when the sash 2l! is in its vertical position, motion of the sash 2l will be transmitted to the block 5l and the said sash properly guided in its motion. When the sash 2l, however, is to be swung inwardly the slidable guide piece 5i will remain stationary and the said sash pivot about the pin 50.. The sill 52 is sloped at its upper surface 53 in a mannerV to eiiect proper drainage and protection from the elements. The lower portion of the removable jamb section 2l is sloped to correspond to the upper portion 53 of the sill 52.

Secured to the sash 28 along that edge normally adjacent the jamb is a metal angle element 54 having a. bent portion 55 which is arranged to slidably engage the wall 56 of the groove 5l formed in that side of the movable stop section 3 l b which is also adjacent the jamb, whereby proper slidable engagement of the sash with the stop is elected. To insure good engagement of the bent portion 55 with the wall 56 a spring member 55 may be secured to the bent portion 55 as illustrated in Figure l. I have provided further engaging means between the lower sash 28 and the stop section 3H) which comprises metallic strap 58 which is secured to the said stop section Sib in a suitable manner and cooperates with the groove 55 formed Within the inner side of the lower sash side wall. With this arrangement, sidewise movement between the stop section 3lb and the sash. 28 is prevented as is their separation. When the lower sash 28 is raised to its vertical position the lock 35 automatically snaps shut securing the stop sections SIb and 3l@ together at their adjacent ends. To further secure the lower stop section 3lb to the jamb section 2l an element 5B comprising a slot 5l may be secured substantially midway between the ends of the stop section 31h for cooperation with the member 32 which has its end 63 so formed as to securely hold the element El! to prevent movement of same toward the center of the sash. To eilect the release of the end 53 of the element 62, from the slot 5l of the element 60, it is necessary to move the said end 63 back into the jamb section 2l through the slot 64 formed within the said jarnb section. It is to be understood that other forms of locking elements may take the place of element Sil and end portion 63, which may comprise locking elements including suitable knobs or other finger grip portions which facilitate operation of the lock.

. The element 62 is secured at its end 65 to the movable middle stop section 30D by suitable fastening means, whereby when movement of the said middle stop section 33h within the jamb section 2i is eiected, as will be explained, oorresponding movement of the end 63 of the element 62 takes place to release the element 63 and permits the stop section Sib to be lowered when the lock 35 is opened by movement of operating element 3S. Another form of locking arrangement which may take the place of elements it and end portion 63 is illustrated in Fig. 1.2 wherein is disclosed a member 62a having hole 66 formed therein for cooperation with wedging member El secured to stop section SIb', wedging element 6l being so formed as to effect, by means of a we-dging action, the tight holding or securing or" the stopy section 3Ib to the jamb section 2l.

To eiect movement of the middle stop section Sb to which is secured the element 62, it is but necessary to lower the sash 28, release `the lock 35, as already described and pivot said sash about the point 49 causing the lower portion 68 of said sash, adjacent the jamb section 2| to engage the lower portion 69 of said movable stop section 30h. That portion 63, of the sash 28 and the lower portion 69 of the movable stop 30h are formed with cam surfaces whereby the operation recited takes place, that is, the sash 28 acts as a lever functioning about the pivot point 49 and the operating portion 68 of the lever effects a camming action against the surface 69 of the movable stop section 30h to cause said movable stop to recede into the jamb section 2| against the action of a pair of springs as will be described.

To normally maintain the middle movable stop section 30h in operative position, as illustrated in Fig. 2, a resilient element such as a spring 10 which may be helical or otherwise, or rubber, is secured to the lower portion of a long flat element 1 I, which in turn is fastened to the movable stop section 30h, and is arranged to urge, by bearing engagement with the wall 12 of the block element 13, the stop section 3th outwardly. It is to be understood that leaf springs or similar means such as for example a lever mechanism or other linkage mechanism may be utilized in the place of the helical springs illustrated in the drawings to eiect the operation described. The. long flat element 1| which is of substantially the same length as the stop section 30h prevents the stop section 30h from protruding through the jamb section 2| more than predetermined distance.. To prevent the transmission of dust and the elements through the window at the places where the movable stop section 30h slidably engages the jamb section 2 I, I may secure to those portions of the element 1| which are adjacent the rear side of the jamb section 2|, a strip or strips of felt or other suitable weatherstripping material. Not only does this make for protection, but it insures quietness of operation.

Aiding the helical spring 'l' in normally urging the stop section 30D outwardly is a second helical spring 1t secured to the removable element 15 incorporated in the jamb section 2|. In assembling the window the end 16 of the helical spring 14 may be secured to the stop section 30h by means of the screw 11. It is to be noted that movement inwardly of the stop section 30h within the jamb section 2| causes corresponding movement of the element 62 which actuates the mechanism vfor securing the stop section 3 lb to the jamb section 2l, as already explained. Not only is the element 15 removable from the jamb section 2|, but the element 18 is likewise removable.

In the operation of mywindow with the sash in the normal vertical position, their movement is effected up and down in the usual manner. In order to bring both sashes, 21 and 28, respectively, within the room, however, it is necessary to first lower the inner sash 28, unlatch the lock by downward movement of the element 38 and swing the said sash 28 inwardly about the pivot point 49, thereby causing camming action to take place between the surface 68 and the surface 69 causing inward motion of the middle stop section 3th and corresponding movement of the element 62, unlocking the second lock which secures the stop 3|b to the jamb section 2l. Before the sash 21 can be swung inwardly, however, it is necessary to manually push the upper portions of the springs 'mand 14 to the position illustrated in Fig. 3. 'I'hen the sash 21 may be swung down as illustrated in Fig. 1 to effect a maximum of ventilation to the interior of the room or to facilitate the washing or painting of the sashes.

The elements 15 and 18 are secured by screws or other suitable means within the jamb section 2l to permit ready assembling and disassembling. Whereas the free end of the helical spring 10 is illustrated in Figs. 2 and 3 as merely bearing against the wall 12 of lthe element 13, it is to be understood that it is within the scope of my invention to modify such bearing surface to a slot or a hole.

Not only is the above described construction readily adaptable to factory production and assembling, but it also may be readily disassembled for service, replacement of parts or the like. In addition to the above advantages the design described readily adapts itself to the conversion of conventional double hung windows to ones operating in accordance with my invention by unskilled workmen.

In Fig. 14 I have illustrated a series of parts mounted on a base 80 which may be applied by a home owner or unskilled workman for use in connection with the conversion of conventional double hung windows. For example, the part 8i may be utilized by securing it to sash 28 as illustrated in Fig. 7 to form a guide when the element 58 is not inherent in the construction of the stop section SIb. The element 82 may be substituted for a cutout portion in the lower part of the side walls or sashes 21 and the element 83 may be substituted for the lower part of the side walls of sash 28. The remaining elements mounted on the base 80 have already been described and may be used as shown in the remaining figures. Not only may the above parts be made of wood, but theymay befabricated of metal or synthetic or other materials. p

Not only may the removable jamb portion 2| be secured to the fixed jamb portion 22 as illustrated in Figs. 8 and 11 but various other expedients may be resorted to as for example, referring to Fig. 15, the element 1lb corresponding to the element 1l illustrated in Fig. 6 may be cut out, or

so formed, at its upper portion as illustrated whereby a leaf spring or equivalent means secured to the portion 22h' may cooperate with the removable portion 2|b at its rear face to hold the organization in proper position, the element 1&2) replacing the helical spring 1G illustrated in Fig. 6. The fixed jamb portion 22h may comprise a removable section 22b as shown which cooperates with the element 40h in a manner similar to the embodiment illustrated in Figs. 8 and 11.

While the elements 1B, 3th and 2| illustrated in section in Figs. 2 and 3 may be individually removable. as shown with the element 18 secured to the jamb section 2l! by means of the screw S or other equivalent fastening means, it is to be understood that it is within the scope of my invention to prefabricate or preassemble the elements 18, 3llb and 15 into a unit which may be incorporated in a window as a unit instead of assembling each element separately. When the removable jamb section is prefabricat-ed as a unit for ready assembly I may utilize different securing means from that illustrated in Figs. 2 and 3. For example, a spring element 1B may be incorporated in the lock 13, an arrangement as illustrated in Fig. 15 may take the place of the spring element 16 in Fig. 6 and other corresponding elements. Further in the place of fastening means S I may utilize a locking `means whereby the portion r2l) may cooperate with the element 11 of the proposed unitary removable jamb section whereby the same will be locked into place when inserted into operative position corresponding to that illustrated in Figs 2 and 3. One type of `mechanism which maybe used as a locking means in place of the fastening means S is the arrangement illustrated in Figs. 2 and 3 involving the elements 6U and 52 or the modication illustrated in Fig. l2 wherein the element 61 cooperates with the hole 66 to eiect a Wedging action. Other equivalent means may be utilized in the relation recited whereby the removable jamb section may be securely held in place.

It will be seen from the above that the window construction in accordance with my invention makes for the provision of a swingable sash window which normally operates precisely as does the conventional double hung window, but has denite advantageous features inherent in its design which comprises the simplicity ci operation required to swing the windows within the interior of a room to permit washing, painting, or service and the practical locking features which are semi-automatic in their operation as well as being fool-proof and dependable.

It will be obvious to those skilled in the art that various changes may be made in this device without departing from the spirit of the invention and therefore the invention is not limited to what is shown in the drawings and described inthe specication but only as indicated in the appended claims.
